Personal Calculator Data Information
Higher calorific kWh values are used throughout.
Household
Carbon dioxide production is given on a per household basis.
Data entered in the form of costs are converted to kWh using current typical domestic prices of electricity, natural gas, diesel heating oil and LPG, and are subject to regular update. No allowance is made for Standing Charges or their equivalent.
Car Travel
Carbon dioxide production is given on a per vehicle basis.
Data entered in the form of costs are converted to kWh using typical forecourt prices of regular unleaded petrol, diesel road fuel and LPG, and are subject to regular update.
Air Travel
a) Carbon dioxide production is given on a per passenger basis.
b) Short, Medium and Long Haul flights are defined in terms of flight distances as follows: Short Haul up to 3000 km, Medium Haul from 3000 to 6500 km, Long Haul from 6500 km up.
c) Flight carbon dioxide production is calculated based on the model given in the report “Calculating the Environmental Impact of Aviation Emissions”, author Dr Christian Jardine, Oxford University Centre for the Environment, 2005.
The assumptions adopted from this model include:
i) Short Haul flights are modelled on the performance of the Boeing B737 400.
Medium and Long Haul flights are modelled as an average of the performances of the Boeing 747 400 and the Airbus A340
Please note that the calculation routines will be updated as more carbon-efficient air transport (for example the A380) comes into significant operation.
ii) It is assumed that the airliner is filled to capacity.
iii) A 10% reduction in carbon dioxide production per passenger is made for Long Haul flights on the assumption that some of the payload is freight.
iv) The final “equivalent” carbon dioxide result is obtained by multiplying the airliner carbon dioxide production figure by a factor of 2 to allow for the increased greenhouse effect of carbon dioxide emitted at higher altitudes.
e). Airliner performance data are from the EMEP/CORINAIR Emission Inventory Guidebook 2006, Group 8, Annex to chapter B851 (published by the European Environment Agency, see: http://reports.eea.europa.eu/EMEPCORINAIR4)

Office
Carbon dioxide production is given on a per office basis.
Data entered in the form of costs are converted to kWh using current typical commercial prices of electricity and natural gas, and are subject to regular update. No allowance is made for Standing Charges or their equivalent.
Data entered in the form of office area and office type are converted directly to carbon dioxide production using data derived from the DETR Energy Efficiency Best Practice Programme Energy Consumption Guide 19 (2000). The average (mean) of the “Typical” and “Good Practice” data are used.
b) Locations are referenced by airport latitude and longitude co-ordinates obtained from A-Z World Airports Online (http://www.azworldairports.com).
c) Short, Medium and Long Haul flights are defined in terms of flight distances as follows: Short Haul up to 3000 km, Medium Haul from 3000 to 6500 km, Long Haul from 6500 km up.

An organization, whose primary directive is to support an issue or matter of private interest or public concern for non-commercial purposes, without concern for monetary profit.
Our time at DWC is spent ensuring the wise investment of clients funds into verified carbon offset programs. Therefore, the nature of our business prohibits any end of year profits for shareholders.
This includes a reduction in the amount of soot particles which we see as the black cloud emitted by some malfunctioning diesel engines (this soot irritates the lungs, and is one cause of bronchitis or asthma).
In addition, with biodiesel, there is a reduction in the emission of carbon monoxide (the culprit when people are poisoned by exhaust fumes), sulphur dioxide (which irritates the airways), and different types of hydrocarbon.
Many of these emissions result from incomplete burning of the diesel fuel. An advantage of biodiesel is that it contains its own store of oxygen (about 11% by weight of biodesel is oxygen), and so it can be burnt more fully in an engine than fossil-fuel diesel.
One particular health benefit with biodiesel is the reduction in emissions of polycyclic aromatic hydrocarbons or PAH. Many PAH compounds have been identified as chemicals capable of interfering with our DNA in ways which can cause cancer and deformities. The total emission of PAHs from diesel exhaust is typically reduced by 75 percent when using biodiesel.
The types of PAH known as nitro-PAH (eg nitropyrene and nitrochrysene) are particularly effective at mutating human DNA. Here biodiesel has an even greater effect, typically reducing nitro-PAH emission by 90 percent plus.
Additionality
It is most important that a project creates new reductions.. This is why we will only invest in a project, if we are confident that the additional reductions would not have happened without our involvement. This means that all the carbon emission reductions that are funded by us will be over and above what would have taken place without our participation.
Additionality is far easier to justify in developing countries that have no official carbon reduction policies and also require investment into carbon reduction projects, which also benefit the life standards of local communities.
Verification and Audit Process
downwithcarbon.org has adopted a stringent protocol regarding the verification and auditing of any project, in which we are involved. We conduct a thorough investigation of any project from the start of our participation. Once the project has received the necessary verification, we conduct a continuous physical monitoring of the operation (Our personnel make regular inspection tours of all our projects). In addition, regular audits are carried out by third party organisations. Our protocol, therefore, ensures total accountability of our investment standards.

Payment Terms
Our business calculator is designed to work out the key CO2 emmissions of your business; taking into consideration company’s travel and power usage.
You (the Purchaser) can either print out a report of your emissions or ask to be invoiced by pressing the invoice button. By asking for an invoice, you are entering into an agreement with downwithcarbon.org – the equivalent of issuing a purchase order – for us to provide services to offset your emissions from the information that you have provided us.
downwithcarbon.org will raise an invoice, which you will receive with a 14-day period and this invoice will be immediately due. Upon receipt of payment downwithcarbon.org undertakes to offset the CO2 emissions specified and subject to this agreement. The amount that you will be invoiced will be subject to VAT at the standard rate.
CO2 Calculations
downwithcarbon.org has made its best endeavours in basing its emission calculations from the most up to date information available from reliable and professional sources and derives its figures from the laws of chemistry. downwithcarbon.org cannot be held liable for any errors or omissions.
Regular reviews are made appertaining to new information regarding greenhouse gas emissions from air travel and other activities. If this information changes, downwithcarbon.org will not be liable to offset any further omissions from previous transactions.
downwithcarbon.org offset emissions are based completely on the information that has been supplied by the purchaser and this information is therefore assumed by us to be correct. We therefore cannot be held responsible for any errors within the report or for any offsets that are outside those mentioned within the report.
Carbon Offset Certificate
- The purchaser of offset credits will receive by email a certificate showing the amount of offsets purchased. The purchaser will not receive title to the emission reductions that have been purchased. When a purchaser makes a payment to offset his/her CO2 emissions, downwithcarbon.org will add the CO2 liabilities by funding CO2 reduction projects on their behalf and over a period to be determined by downwithcarbon.org on a business as usual basis. Included in the cost of the emission units will be factors including administration of the projects.
- downwithcarbon.org undertakes not to sell any emissions reductions to more than one party.
- downwithcarbon.org undertakes to ensure to the best of their ability the additionality of their projects.
- downwithcarbon.org ensures the verification of all its projects.
